BOOK-REST.

SPECIFICATION forming part of Letters Patent No. 359,056, dated March 8,1887.

Application filed November 4, 1886. Serial No. 217,932. (No model.)

To all whom it may concern:

Be it known that I, ADDISON G. BROWER, ofPlymouth, in the county ofWayne and State of Michigan, have invented new and useful Improvementsin Book-Rests; and I- do hereby declare that the following is arfull,clear, and exact description thereof, reference being had to theaccompanying drawings, which form a part of this specification.

This invention relates to an improvement in book-rests; and theinvention consists in the peculiar construction of a friction-hinge, bymeans of which the rest is made adjustable to any desired inclination;and it also consists in a novel construction, arrangement, andcombination of different parts, all as hereinafter more fully described,and specifically set forth in the claims.

In the drawings which accompany this specification, Figure 1 is aperspective view of my improved book-rest. Fig. 2 is a cross sectionthrough one of the hinges, as indicated by the line 00 w in Fig. 1. Fig.3 is aperspecv tive view of the parts described.

A is the inclined rest, which is secured to a suitable foot. B, by meansof hinges O, which are constructed as follows: A cleat. D, is securednear the front edge of the foot, and this cleat is rounded off upon itsends to form the hinge-pins E, to which are secured the leafsprings F.

G are straps of sheet metal preferably spring metalsecured to theinclined rest A, and forming with their free ends the eyes H of thehinges, which are formed open and provided with adjusting-screws I, bymeans of which said eyes may be made smaller orlarger. The relativesizes of the eyes of the hinges and the hinge-pin are such that an openspace is formed between them,within which the springs F may be freelycoiled around the hinge-pin,

and by their frictional contact with the eye of the hinge producesufficient friction to hold the rest A at any desired inclination, thescrews I permitting of increasing or diminishing such friction, as maybe found convenient, to counteract the weight of the rest andsuperimposed book.

J is a stop secured to the lower end of the rest, and K is a bail madeof spring-wire and provided with eyes L, by means of which it is securedin frictional engagement upon the ends of the stop J in suitable annulargrooves, so that the eyes Lwill holdthe bail K sufficiently firm uponthe leaf of the book to prevent its displacement when turned down uponthe leaf of the book.

The ends of the hinges are preferably covered over by cheeks M, securedto the foot B.

NVhat I claim as my invention is- 1. In a book-rest,the combinationofthe inclined rest A, the foot B, and the frictionhinges O, connectingsaid foot and rest, and means for increasingor decreasing the friction,substantially as described.

2. In a bookrest, in combination with the inclined rest A and foot B,the friction-hinge G, consisting ofthe hinge-pin E, the strap G, havingeye H, the adj llSllllg-SGIQW I, and the spring F, secured to thehingepin and inclosed within the eye-of the hinge, substantially asdescribed.

3. In a book-rest, the combination of the inclined rest A, the stop J,and the bail K, provided with the eyes L, engaging by frictional contactin annular grooves of the stop J, all substantially as described.
